title: Gateworks System Controller

description: |
  The Gateworks System Controller (GSC) is a device present across various
  Gateworks product families that provides a set of system related features
  such as the following (refer to the board hardware user manuals to see what
  features are present)
   - Watchdog Timer
   - GPIO
   - Pushbutton controller
   - Hardware monitor with ADC's for temperature and voltage rails and
     fan controller

maintainers:
  - Tim Harvey <tharvey@gateworks.com>

          Properties for a single ADC which can report cooked values
          (i.e. temperature sensor based on thermister), raw values
          (i.e. voltage rail with a pre-scaling resistor divider).
